HoloJS with HoloLens 2 about holojs

[daniele-bordignon-kodis]

If I manually add the missing DLLs app runs on device (ARM platform) But if I try to use the API I get errors:
%1 is not a valid win32 app

I found there is a vs2019 branch but I cannot understand how to use that.
Tried following build instructions but cannot find all the files to build
(is there an already built win32 holojs version to just link in nuget?)

You are not doing anything wrong; it's just that HoloJS does not support HoloLens 2. There is no ARM64 HoloJS NUGET package and consequently the binaries are missing when you deploy the app.

Since HoloJS is using multiple open source projects to assemble its dependencies (ANGLE, LabSound, Canvas API, etc.), all of these projects would have to be built for ARM64 in order to support HoloLens 2.

I see. So how am I supposed to build apps for HoloLens 2 with HTML and JS?
Is there a way?
Sorry, I know this is ot but I dinged a lot of documentation and stack overflow but most of them refers to HoloLens V1, even official Microsoft documentation I think.

I don't know of a way to build HTML/JS apps for the HoloLens 2. These would be apps that you can install and/or submit to the store.

However, you could build immersive web apps that run in the web browser on HoloLens 2 using WebXR. See https://docs.microsoft.com/en-us/windows/mixed-reality/develop/javascript/webxr-overview

Web apps would be limited to the capabilities of WebXR - a subset of HL2's capabilities. I believe there is no web standard that would give you access to surface reconstruction, voice commands, etc.

Thank you a lot.
I already checked that I can run 3D capable webapps on a browser but my purpose was to encapsulate them.
I already developed apps with Ionic so I'm used to work on web technologies (so they are my first choice) and then upload them on the stores.

@daniele-bordignon-kodis try Buildwagon , it is javascript development for Hololens 2 with full access to the device features like: spatial understanding, eye gaze, voice commands, azure spatial anchors... You can also package your app and upload it to the store, just like ionic.
